Can someone describe from a network point of view what RPC (SUN and/or DCE) is and why it deviates from standard TCP behavior? The way that I understand it is a client reaches out to a server with a unique source port and then switches the source por...

Is there a way to perform multiple filters to a show command in the Cisco ASA IOS (8.4 and above)? Please give an example if there is. I tried:show access-list | include 10.15.221.22 | exclude 1270but that does not work.

Thanks. So does the explanation of, "This will not work on the ASA device" refer to my example or does it refer to any kind of multiple filter syntax? In other words do ASA devices not support muliple show command filter syntax?

Ok, so any kind of explanation of fast path and session management path might be helpful. Does the firewall route the return trip based on its routing table?

Mike Keenan · 07-09-2015
